The Sword Spirit of a divine sword, especially one that has developed its own consciousness, should by all means be incredibly difficult to control.
Even for the sword's master, without substantial strength, there is no guarantee of full recognition by the Sword Spirit. It might even backfire, subjugating the wielder to become its servant.
Tristan was probably the most adept swordsman among them, and he too believed that William couldn't possibly command such a powerful Sword Spirit.
However, in front of William, the Sword Spirit really became like a child. Hearing William's command, it murmured softly, "And to spare this person's life... controlling power to such an extent is too difficult..."
Listen to that, aren't these words hurtful?
In his agitation, Lucien hurriedly said, "Can't I just not fight? Is that okay?"
What a joke.
